The Verdict
The Tanita BC-558 Ironman Segmental Body Composition Monitor is a professional grade body composition scale that may overwhelm some people on first use. While it is one of the most accurate body composition monitors on the market, it does take some time to calibrate.

The readings are at the same accuracy level you’d get at a professional fitness center, making it a good scale for professional fitness athletes. Nonetheless, amateurs might not value this level of accuracy considering the high price tag.

Like other Tanita body composition monitors, it uses Bioelectrical Impedance Analysis (BIA), which is acknowledged as one of the most accessible and reliable methods of screening body fat. The difference between this device and some of the lower cost scales on the market is the ability to measure different segments of the body independently. Typically body fat scales only take readings from the feet, which can lead to inaccurate results depending on a number of factors. That is not the case with the Tanita BC-558.

Overall, this is one of the most accurate body composition monitors you can buy and is best suited for professionals or those who are willing to spend 10x for that accuracy. For recreational users your money may be better spent on a lower cost scale that offers features like bluetooth connectivity and fitness tracking.
